Great tutorial! Just to mention: to see glass in the Blender viewport you need to add an UVMap and a vertex color to your glass object. Some of materials needed some preperataion befor they will work right, for glass it will be an UVMap and a vertex color on the object's mesh. Using UVMap and vertex color you also can add some sharpness to some of object's parts.
